AUTOMOBILE SWITCH-LOCK.

Specification of Letters Patent.

Patented May 13, 1919 Application filed November 29, 1918. Serial No. 264,572.

To all whom it may concern:

Be it known that I, JOHN H. SHAW, of the city and county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Automobile Switch-Locks, of which the following is a full, clear, and exact description.

This invention relates to looks and more particularly to novel means for securing a pin tumbler lock in place within a receptacle or the like, in which the same is to. operate, this application being a continuation in part of my earlier application, Serial No. 246,127, filed July 22, 1918.

The primary object of this invention is to provide a cylinder lock with means for engaging the opposite walls of a receptacle or the like in which it is mounted to thereby retain the lock in its operative position within the receptacle.

Another object of my invention is to provide a cylinder lock with projections constructed to be seated in the opposite walls of a receptacle or the like, in which it is mounted, whereby the meansv which retain said opposite walls in their spaced relation also retain the cylinder lock in place Within the receptacle.

Still another object of my invention is to provide a switch casing or the like having manually operable switches therein with very simple key controlled means for looking said switches so that they cannot be operated by an unauthorized person.

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings:

Figure 1 is a front elevation of a Wellknown type of automobile switch casing having my improved cylinder lock mounted therein.

Fig. 2 is a sectional view of Fig. 1 taken on th line 2-2 looking in the direction of the arrows.

Fig. 3 is a view of the inner face of the rear wall of the switch casing ,shown in Fig. 1, with my cylinder lock in its operative position.

Fi 4 is a view similar to Fig. 3, but showmg the cylinder lock out by a section taken on the line 4-4 of Fig. 2.

Fig. 5 is a sectional view taken on the line 5 -5 of Fig.1.,

Fig. 6 is a fragmentary view of the inner face of the rear wall of the casing showing the sockets formed therein for one end of my cylinder lock, and

Figs. 7 and 8 are plan and side views re spectively of my cylinder lock removed from the switch casing.

In the drawings, I have designated by the numeral 10, a well-known type of automobile switch casing, which is commonly mounted upon the instrument or dash board of an automobile. This type of switch casing is commonly provided with a pair of switch levers, such as 11 and 12, by means of which the electrical switches contained within the casing 10 may be turned 0H and on. This type of switch casing usually consists of a sheet metal plate or disk 13,

which is firmly secured to a cup-shaped desiredinsulating material, such as ebonite.

The disk member or rear plate 16, fits snugly within the cup shaped member 14, and is provided adjacent its outer face with the annular shoulder 17, against which the rear edge of the cup-shaped member 14 abuts. The member 16 has a drill hole formed centrally therethrough to receive the rear wardly projecting post 15, which is threaded, and is provided. with a threaded nut by means of which the rear plate 16 may be clamped to the cup shaped member 14. The instrument or dash board (not shown) is usually provided with a cylindrical opening in which the cup-shaped member 14 may be snugly mounted, the marginal portion of the disk 13 contacts with the forward face of the instrument board and covers the opening, just mentioned. The construction of the switch casing, so far described, is well known, and since it forms no part of my invention, further description is unnecessary.

The locking means which I provide for locking the switch levers 11 and 12, so that they cannot be operated, consists of a plate post 15, and is slidably retained in place 7 upon the inner face of the member 16 by any desired means such as pins 21, which, extend through elongated slots -22 formed adjacent the opposite ends ,of the plate 18. In order to hold the plate 18 against accidentalmoye nent, when it has been shifted to one end f itspath of .movementorthe other, I provide,aspringoperated -P.aw1-23, which is pivotally mounted npo naipin 2{L, mounted in the rear wall .16. The forward end of thepawl 23 is p rov-ided .with a rounded nose, which engages oneortheotherof the notches 25 formed gin-an edge of the plate 1 8, the pawl being held in engagement with the plate 18- ;by the spring .26. Inorder to provide ,means by which-the cylinder lock herenat e de c i d m y cr m -the Plate I I form an-iega tension 27 upon this plate,

therouterrendaofwhich is bent at-right angles tothis extension as shown, at 28 in Fig. 5 of the-drawing. Since my invention relates to the censtrnction of thelock, which operates the sliding plate 18 and does not relate to the mechanism ,by which theplate .1 8 locks the switch levers lland 12 against movement, I have not atten pted ,to disclose .01 describe the cooperating means between the plate 18 and" the switch mechanism operated by the leuerslland 12, it being obvious .that any preferred mechanism may .be used for this purpose without in any way affecting the construction or the-mountingof my eylinder lock ;-hereinatter described, within its receptacle.

The cylinder lock which-I have disclosed in the drawings consists ofa lock case 29 having the usual pin tumbler extension 30 with the usual pin tumblers 131 slidably mounted therein. -Retatably mounted in the :lock case 29isgnountedethe usual type-of key barre132 the forward; end 0f=which projects beyond vthefcase w as at 33 and is;provided with-the :usuahshoulder .which engages the forward face 0;f':the case 29in a-well known manner. The shoulder just mentioned prevents the key plug fI'OH-l sliding within the case in rearward directien and the laterally ,proj ecting pin 3,4, nounted in the key plug adjacent the rear end thereof contacts with t the rear face 13511 0 1 2 a d 1p Vents-the key Pl g iroms id ng 5 1 7 ppos'ite direction. ,Uponthe case29 lS fol fllle il a plurality of rearwardlyprojecting lugs 35, two rlugsybeingshown in the construction Tl'lQSB ;lu gs, should Joe noted are spaced laterally from the key plug 32, a sufficient distance to permit-theouter end ;of='the;pin-34@ to clear these lugs ,whenathelmy 12 .1 g is" rotated by its The means which I provide for operatively mounting my cylinder look within the s'witeh"casing *consis-ts "in forming a drill l1ole'*through'= the --fron't="wall of the switch casing in order that the forwardly projecting end 33 of the key plug may project throiwh this opening, the same being constructe to form a bearing in which the head .33 rotates. The outer end of the key plug 32 is thus permitted to project through the front face oftheswitchcasing. (asshown in Fig. 1 in .vorder that the key 36 may readilybeainserted in the same. In the rear wall 16 of the switch easingopposite the opening, just mentioned, formed a pocket or clearance .sp ace; 37 .in which ther pro ecting pin Mmayswing when the key-plug :is retated; also, if desired, a second pocket 38 may be ,formed'in the wall 16 to clear the rearward.projecting end.of the keyplug 32, should this key plug extend some "distance beyond therea'r faeelo f thecase 219. Inaddition to .the pockets just mentioned, sockets 39 (as shown in Fig; 6-) are formed in the plate :16 to snugly receive the rearwardly projecting lugs .35 so that when these lugs arelseated in said sockets thelock case29 is Pre d- 5mm rot inglith .lens fhb the case 29 issuchthat the forwardfaceof this case will abut againstthe inner face of. thecup. shaped-member 14, as shown in Figs. 2 and 5, whenthe =1ngs 35 ,are seated in the sockets 39, it .willgbe seen that the lock case willlbefirmly retained in place. I

lilrom the above description when read inconnection with the.drawings, it will be seen that if my cylinder lock is mounted within the switch casing, with one end projecting nt th op n n f med i'n tihe inw d wa of th asing, a d i h lug p n t pp s e d P jec ing intorthes t 3 the lock will be ,iigidly 56011I$d in place ,by the front and rear wall of the switch casing. It will. alsobe apparent, that in the. construction herein disclose-d, it is unnecessary to rigidly secure my cylinder lock to any. element oft'he switch casing before the parts of the casing are assembled, for when the parts of the casing are secured in place by the nut upon the post 15,,my cylinder lock will be clamped betweenthe frontand-rear wall of the switch casinga nd will be rigidly secured in place by the construction abowiederscribed.

=Whenany;cylindenlockjs mounted in the i switch casing in the manner above set forth, he id ng p t 1 :may b s we by roati s h key Plu 2,-d1. toh tes ha the pin 3fli's so positioned that it engages either one side or the other of the -bent end 28 formednpon theeirtension insertin-gthe key 3 6 ,wgith in -its;key plug androtating the same,- vthe pin .351 will he movedout. of contact with bus vita'ee of the member 28 and will be swung through suhstantially 13 9;.

a complete circle to engage the opposite side of this member 28, whereupon the pin 34 will move the sliding plate 18 to the left, with respect to Fig. 4. It will thus be seen that the key plug 32 not only operates the sliding plate 18 by means of the pin 34, but also locks this plate in either its operative or inoperative position, for when the key 36 is removed from its key plug, the plug is locked against rotation in a well known manner, and the pin 34 is thereby retained in the position shown in Fig. 4, in which position it prevents the plate 18 from moving in a left hand direction; and if the key plug is operated by its key to move the plate 18 in a left hand direction with respect to Fig. 4:, the key plug upon being rotated through a complete revolution will lock the plate 18 in its new position in' the manner above pointed out, as the pin 34 will the-n be held in engagement with the opposite side of the member 28.

Although I have disclosed my cylinder lock as mounted within an automobile switch casing, it will be apparent that the means herein disclosed for retaining my cylinder lock in place between a pair of spaced walls may be used in connection with various devices other than the automobile switch casing herein shown.
